Introduction 

THE  Consolidated  Safety  Valve  Company  has  within  the  last  two 
years  inaugurated  two  exceedingly  important  movements  in  the 
safety  valve  practice  of  this  country — movements  which  are 
causing  universal  modifications  of  design,  and,  for  the  first  time  in  the 
history  of  engineering,  are  putting  the  methods  of  safety  valve  rating 
and  specification  upon  a  sound  basis.  This  has,  of  course,  required 
exhaustive  testing  and  research,  in  conducting  which  this  Company 
has  spared  no  expense,  deliberately  adopting  the  policy  of  giving  the 
results  freely  to  the  engineering  public.  This  policy  has  obtained 
for  the  Company  in  this  work  the  co-operation  of  railroads,  of  station- 
ary and  marine  interests,  and  of  eminent  engineers,  adding  much  to  the 
broad  application  and  value  of  the  results  obtained. 

The  movements  referred  to  are  :  first,  for  the  rating  and  specifying 
of  safety  valves  according  to  their  actual  relieving  capacities ;  and, 
second,  for  increasing  their  efficiency  by  modifications  in  design  which 
make  possible  the  obtaining  of  larger  capacities,  and  a  cleaner,  more 
positive  action.

Safety   Valve   Capacity 


A"  J  account  of  certain  of  the  elaborate  tests  and  extensive  research 
work,  conducted  by  this  Company,  showing  the  apparatus 
developed,  the  methods  employed  and  results  obtained,  has 
been  published  in  a  pamphlet  entitled  "  Safety  Valve  Capacity,"  which 
will  be  sent  upon  application  to  anyone  interested  in  this  subject. 
Because  of  this  supplementary  publication,  the  following  account  of  the 
work  will  be  brief. 

The  function  of  a  safety  valve  is  to  prevent  the  pressure  in  the 
boiler,  to  which  it  is  applied,  from  rising  above  a  definite  point ;  to 
do  this  automatically,  and  under  the  most  severe  conditions  which 
can  arise  in  service.  For  this  the  valve,  or  valves,  must  have  a  reliev- 
ing capacity  at  least  equal  to  the  boiler  evaporation,  under  these  con- 
ditions. If  it  has  not  this  capacity,  the  boiler  pressure  will  continue 
to  rise,  although  the  valve  is  blowing,  resulting  in  strain  to  the  boiler 
and  danger  of  explosion,  consequent  to  over-pressure.  Thus,  with  the 
exception  of  a  requisite  mechanical  reliability,  the  most  vital  factor  in 
a  safety  valve  is  its  capacity. 

Two  factors  in  a  safety  valve  geometrically  determine  the  area 
of  discharge  and  hence  the  relieving  capacity.  These  are  the  diame- 
ter of  the  inlet  opening  at  the  seat,  and  the  valve  lift.  The  former 
is  the  nominal  valve  size;  the  latter  is  the  amount  the  valve  disc  lifts 
vertically  from  the  seat  when  in  action.  The  rules  for  calculating 
the  size  of  valves  to  be  placed  on  boilers,  which  do  not  include  a 
term  for  this  valve  lift,  or  an  equivalent  (such  as  a  term  for  the  effective 
area  of  discharge)  assume,  in  their  derivation,  a  lift  for  each  size 
valve.  Nearly  all  existing  rules  and  formulae  are  of  this  kind,  which 
rate  all  valves  of  a  given  nominal  size  as  of  the  same  capacity. 

To  find  what  lifts  valves^ actually  have  in  practice,  and  thus  test 
the  truth  or  error  of  this  assumption,  that  lifts  are  approximately  the 
same  for  the  same  size  valve,  an  apparatus  has  been  devised  by  us 
upon  which  tests  of  different  designs  of  valves  have  been  conducted. 
With  this  apparatus,  not  only  can  a  valve  lift  be  read,  at  any  moment, 
to  thousandths  of  an  inch,  but  an  exact  permanent  record  of  the  lift,

during  the  blowing  of  the  valve,  is  obtained.  This  record  resembles 
a  steam  engine  indicator  card  in  appearance,  and  is  of  similar  use  and 
value  in  analyzing  the  action  of  the  valve. 

As  appears  in  illustrations  on  pages  4  and  5,  the  valve  under  test 
is  mounted  upon  the  boiler  in  the  regular  manner,  and  a  small  rod  is 
tapped  into  the  top  end  of  its  spindle.  This  rod  connects  the  lifting 
parts  of  the  valve  directly  with  a  circular  micrometer  gauge  and  a 
recording  gauge  above.  The  steam  pressures  are  noted  and  read  from 
a  large  test  gauge,  graduated  in  pounds  per  square  inch,  and  an  electric 
spark  device  makes  it  possible  to  spot  the  chart  at  any  point  in  its 
travel.  In  our  tests,  this  was  done  as  each  pound  pressure  mark  was 
reached,  during  the  blowing  of  the  valve.  The  actual  lift  equivalents 
of  the  pencil  heights  upon  the  chart  are  carefully  calibrated  in  order 
that  the  record  may  be  accurately  measured  to  thousandths  of  an  inch. 

With  this  apparatus,  investigations  and  tests  were  started  upon 
seven  different  makes  of  4-inch  stationary  type  safety  valves,  and  these

tests  were  followed  by  similar  ones  upon  nine  makes  of  muffler  loco- 
motive valves,  six  of  which  were  3^-  inch.  All  these  valves  were 
designed  for  and  tested  at  200  pounds  steam  pressure.  The  stationary 
valve  tests  were  made  upon  a  94  horse-power  Babcock  &  Wilcox 
Company  water-tube  boiler.  The  locomotive  valve  tests  were  made 
upon  locomotive  No.  900  of  the  Illinois  Central  Railroad,  the  valve 
being  mounted  directly  upon  the  top  of  the  main  steam  dome.  Al- 
though a  great  amount  of  additional  valve  lift  experimental  work  has 
been  conducted,  the  above  two  series  only,  will  be  quoted  here.  The 
record  of  lifts,  given  in  table  on  page  6  shows  (with  exception  of  a 
small  preliminary  simmer,  which  some  of  the  valves  have)  an  abrupt 
opening  to  full  lift  and  an  almost  equally  abrupt  closing,  when  a  cer- 
tain lower  lift  is  reached.  Both  the  opening  and  closing  lifts  are 
significant  of  the  valve  action.

The  great  variation — 300  per  cent — in  the  lifts  of  these  standard 
valves  of  the  same  size  is  startling.  Its  real  significance  is  apparent, 
when  it  is  realized  that  under  existing  official  safety  valve  rules,  these 
valves,  some  of  them  with  less  than  one-third  the  lift  and  capacity  of 
others,  receive  the  same  rating  and  are  listed  as  of  equal  relieving  value. 
There  are  other  defects  in  existing  rules,  as  indicated  in  the  pamphlet 
above  referred  to.  For  example,  in  these  rules,  the  assumed  lift  varies 
as  the  valve  diameter,  while  in  reality,  with  a  given  design,  the  lifts  are 
more  nearly  the  same  in  the  different  sizes,  not  varying  nearly  as  rapidly 
as  the  diameters.  And  further  than  this  the  lifts  assumed  in  these 
rules,  for  the  larger  valves,  are  nearly  double  the  average  actually 
obtained  in  practice. 

The  direct  conclusion  is  this:  that  existing  rules  and  statutes  are 
not  safe  to  follow.  Some  of  these  rules  were  formulated  before  spring 
safety  valves  were  invented  and  at  a  time  when  1 20  pounds  was  con- 
sidered high  pressure.  They  have  not  been  modified  since.  None  of 
them  takes  account  of  the  different  lifts  which  exist  in  the  various 
makes  of  valves  of  the  same  nominal  size.  It  would  therefore  seem 
the  duty  of  all  who  are  responsible  for  steam  installation  and  opera- 
tion, to  investigate  for  themselves  and  no  longer  leave  the  determina- 
tion of  safety  valve  size  and  selection  to  such  statutes  as  may  happen 
to  exist  in  their  territory. 

The  elements  of  a  better  rule  for  determining  safety  valve  size 
exist  in  Napier's  formula  for  the  flow  of  steam,  combined  with  the 
actual  discharge  area  of  the  valve,  as  determined  by  its  lift.  By  sub- 
stituting the  value  of  the  effective  area  of  discharge,  with  a  45  degree 
seat,  into  Napier's  formula,  the  following  is  obtained — E  =  1 14  x  L  x  P 
x  D,  in  which  E  is  the  valve  relief  or  capacity  in  pounds  of  steam  per 
hour;  L  is  the  vertical  lift  of  valve  in  inches;  P  is  the  boiler  steam 
pressure  (absolute)  in  pounds  per  square  inch ;  D  is  the  nominal 
diameter  of  the  valve  in  inches,  i.e.,  the  diameter  of  the  inlet  opening. 

The  uncertainty  of  the  coefficient  of  flow,  that  is,  of  the  exact 
value  of  the  constant  in  this  formula,  when  applied  to  the  irregular 
steam  discharge  passages  of  safety  valves,  has  probably  been  largely 
responsible  for  the  fact  that  this  method  of  obtaining  valve  capacities 
has  not  been  more  generally  used.  To  determine  what  this  constant, 

8 


Consolidated         Pop         Safety        Valves 

or  coefficient  of  flow,  is  and  how  it  is  affected  by  variations  in  valve 
design  and  adjustment,  the  Consolidated  Safety  Valve  Company  has 
recently  conducted  an  extended  series  of  tests  at  the  Stirling  Depart- 
ment of  the  Babcock  &  Wilcox  Company  at  Barberton,  Ohio. 

A  373  horse-power  Stirling  boiler  was  used,  its  water  feed  being 
measured  in  calibrated  tanks  and  the  entire  steam  discharge  from  the 
boiler  being  through  the  valve  under  test.  Three  sizes  of  stationary 
type  and  three  of  locomotive,  the  latter  with  and  without  mufflers,  all 
being  Consolidated  designs,  were  used  in  this  work.  There  were  run 
29  separate  tests,  most  of  which  were  of  three  hours  duration.  Much 
information  concerning  the  design,  action  and  theory  of  safety  valves, 
was  obtained  from  these  tests.  The  most  important  application  of 
the  results,  however,  was  in  determining  directly  from  actual  tests 
upon  safety  valves  themselves,  a  value  for  the  constant  in  the  capacity 
formula  already  indicated.  This  value  obtained  from  these  tests  is 
105,  giving  as  the  capacity  formula 

E  =  105  x  Lx  P  x  D 
or  transposed 

E 


To  make  the  use  of  the  rule  more  direct,  where  the  evaporation 
of  the  boiler  is  only  indirectly  known,  it  may  be  expressed  in  terms  of 
the  boiler  heating  surface  or  grate  area.  This  modification  consists 
merely  in  substituting  for  the  term  E  (pounds  of  total  evaporation),  a 
term  H  (square  feet  of  total  heating  surface)  multiplied  by  the  pounds 
of  water  per  square  foot  of  heating  surface  which  the  boiler  will  evapor- 
ate. Evidently  the  value,  of  such  modified  forms  of  the  formula, 
depends  upon  the  proper  selection  of  average  boiler  evaporation  figures 
for  different  types  of  boilers  and  also  upon  the  possibility  of  so  grouping 
these  boiler  types  that  average  figures  can  be  satisfactorily  selected. 
Such  values  have  been  suggested  and  are  given  in  our  book  entitled 
"  Safety  Valve  Capacity." 

In  locomotive  practice,  special  conditions,  as  the  relation  of  the 
required  safety  valve  capacity  to  the  maximum  evaporative  capacity  of 
the  boiler,  make  the  form  of  the  rule,  based  upon  heating  surface,  more 
serviceable  than  the  above  more  direct  form.  In  the  first  place,  the 


Consolidated          Pop         Safety         Valves 

maximum  evaporation  of  a  locomotive  is  only  possible  with  the  maxi- 
mum draft  obtained  when  the  cylinders  are  exhausting  up  the  stack,  at 
which  time  the  throttle  is  necessarily  open.  The  throttle,  being  open, 
is  drawing  some  of  the  steam  and  therefore  the  safety  valves  on  a  loco- 
motive can  never  receive  the  full  maximum  evaporation  of  the  boiler. 
Just  what  percentage  of  this  maximum  evaporation  the  valve  must  be 
able  to  relieve  under  the  most  severe  conditions,  can  only  be  determined 
experimentally. 

A  large  number  of  service  tests  have  been  conducted  to  determine 
the  constant  in  this  formula.  The  size  valves  upon  a  locomotive  have 
been  increased  or  decreased  until  one  valve  would  just  handle  the  maxi- 
mum steam  generation,  and  the  locomotive  heating  surface  being 
known,  the  formula  was  figured  back  to  obtain  the  constant.  Other 
special  conditions  were  considered,  such  as  the  liability,  in  locomotive 
practice,  to  a  not  infrequent  occurrence  of  the  most  severe  conditions; 
the  exceptionally  severe  service  which  locomotive  safety  valves  receive; 
and  the  advisability  on  locomotives  to  provide  a  substantial  excess 
valve  capacity.  The  rule,  thus  selected  for  determining  the  proper 
safety  valve  equipment  for  locomotives,  is  : 


D=     .055   - 


H 


L  x  P 

in  which  D  is  the  nominal  valve  diameter  in  inches;  H  is  heating 
surface  in  square  feet ;  L  is  the  safety  valve  lift  in  inches ;  P  is  boiler 
pressure  (absolute)  in  pounds  per  square  inch. 

Two  direct  results  have  issued  from  the  extended  investigations, 
briefly  indicated  above. 

ist.  The  complete  redesign  of  the  entire  line  of  Consolidated 
Safety  Valves. 

2nd.  The  possibility  of  incorporating,  in  this  catalogue,  tables 
giving  the  relieving  capacities  of  each  valve.  These  capacities  are 
stamped  upon  the  valves,  and  constitute  the  Company's  guarantee  of 
their  relief.  In  presenting  them,  the  Consolidated  Safety  Valve  Com- 
pany takes  the  lead  in  giving  to  designing  engineers  the  first  reliable 
data  upon  which  to  base  safety  valve  specifications,  thus  starting  a  new 
era  in  the  history  of  safety  valve  practice.

Consolidated  Safety  Valve  Designs 


THE  feature  which  has  predominated  in  the  redesigning  of  Con- 
solidated Safety  Valves  is  the  large  and  generous  spring.  With 
each  type  of  valve,  a  spring  of  suitable  proportions,  having  de- 
sirable values  for  both  fiber  stress  and  compression  under  the  highest 
steam  pressures,  was  first  calculated  and  the  valve  case  was  then  built 
up  around  this  spring.  Steam  pressures  have  outgrown  the  spring 
spaces  available  in  valve  cases  not  recently  enlarged.  Only  by  a  com- 
plete redesign,  such  as  that  undertaken  by  the  Consolidated  Safety 
Valve  Company,  can  the  unavoidable,  extreme  values  for  these  two 
spring  factors,  which  result  from  the  limitations  of  a  contracted  spring 
chamber,  be  remedied  and  values,  efficient  at  the  steam  pressures  of 
present  practice,  be  maintained.  The  policy  of  Consolidated  spring 
design  is  for  comparatively  large  spring  diameters,  which  design  gives 
springs  of  more  mechanical  stability  than  those  of  long  slender  propor- 
tions, and  makes  possible  the  maintenance  of  lower  fiber  stresses  for 
given  compressions. 

An  absolutely  central  thrust  of  the  spindle  upon  the  valve  feather 
(or  disc)  and  freedom  of  the  spring  from  the  least  tendency  to  cramp 
or  bind  the  spindle  have  been  obtained  by  the  exceptionally  flexible 
method  of  mounting  the  spring  to  the  end  of  the  compression  screw 
above  and  to  the  spindle  below.  This  consists  of  two  ball  and  socket 
bearings  of  the  same  size  (making  the  top  and  bottom  spring  washers 
interchangeable)  which  allows  the  spring  ends  to  freely  assume  their 
normal  positions. 

A  distinguishing  feature  of  the  valve  feather  is  the  fact  that  its 
upper  trunk  overlaps  the  outside  of  the  spring  case.  This  leaves 
practically  no  area  upon  the  top  of  the  feather  exposed  to  exhaust  steam 
pressure,  the  principal  advantage  of  which  is  that  it  makes  the  feather 
entirely  independent  of  pressure  conditions  within  the  valve  case.  This 
construction,  which  will  be  found  in  all  forms  except  H  to  O  inclusive, 
also  gives  an  exceptionally  effective  protection  to  the  spring  and  makes 
possible  a  more  compact  spring  case. 

Another   exclusive    feature  of  Consolidated  valves   is  the  balled 


Consolidated         Pop         Safety         Valves 

seat,  included  in  each  of  the  designs.  The  seats  are  hand  ground  with 
a  spherical  balling  tool  which  maintains  a  perfect  bearing  at  the  seat 
despite  any  axial  change  of  the  feather  position.  This  construction  is 
largely  responsible  for  the  exceptional  tightness  of  Consolidated  valves. 

The  long  broad  faced  wings  of  the  feather  below  the  seat  and  the 
ample  bearing  of  its  trunk  on  the  spring  case  above,  together  with  the 
unusually  low  bearing  of  the  spindle  upon  the  feather,  make  the  lift- 
ing of  the  valves  smooth  and  free  and  give  them  their  characteristic, 
clean,  positive  action. 

The  blow  back  adjustment  of  all  Consolidated  valves  is  obtained 
by  means  of  the  original  device  for  this  purpose,  the  Richardson  Ad- 
justing Ring.  Many  equivalent  devices  for  this  purpose  have  from 
time  to  time  been  introduced,  but  none  has  ever  equalled,  either  in  effi- 
ciency of  regulation  or  simplicity  of  construction,  this  Richardson  ring, 
the  invention  of  which  marked  the  origin  of  pop  safety  valve  design. 
It  not  only  gives  a  definite,  positive  control  of  the  blow  back  adjust- 
ment for  close  or  wide  regulation,  but  forms  an  important  factor  in 
obtaining  the  large  relieving  capacities  of  these  valves. 

The  arrangements  of  the  lock  up,  lifting  lever  and  pressure  adjust- 
ment are  all  of  newly  patented  design.  They  are  very  compact, 
simple,  and  at  the  same  time,  effective.  The  relief  nut  upon  the  top 
of  the  stationary  valve  spindle  makes  it  possible  to  take  apart  the  valves 
for  regrinding  or  inspection,  without  disturbing  either  adjustment  of 
the  valve — a  detail  of  great  practical  advantage  in  service. 

In  each  type  of  Consolidated  valve,  analysis  will  show  an  absolutely 
minimum  number  of  parts,  which  is  due  to  the  consistent  following 
of  the  simplest  and  most  straightforward  design. 

The  materials  of  construction  employed  have,  in  each  case,  been 
selected  for  the  particular  service  which  the  part  will  receive.  All 
springs  are  of  the  best  grade  crucible  spring  steel.  In  form  A,  casings 
and  covers  are  of  iron,  the  bushings  and  other  mountings  of  special 
bronze  composition,  except  the  seat  which  is,  in  all  cases,  of  nickel — a 
metal  which  has  proven  itself  pre-eminently  satisfactory  for  this  pur- 
pose, being  absolutely  non-corrosive  and  capable  of  withstanding  the 
severest  oxidizing  action.

Stationary  type,  form  B,  has  casing  of  steel,  bushing  and  other 
mountings  of  nickel.  This  metal  is  especially  suitable  for  use 
with  steel  in  this  high  temperature  service  as  it  maintains  its  tensile 
strength  and  has,  besides  its  non-corrosive  properties,  a  coefficient  of 
expansion  very  close  to  that  of  steel.  This  feature  is  very  necessary  at  high 
temperatures  to  prevent  the  loosening  of  the  seat  and  cover  bushings. 

All  nickel  mountings  in  form  B  valves  are  securely  locked  in 
place  by  spinning,  which  acts  as  a  further  preventative  against  these 
parts  becoming  loose  under  high  temperatures. 

Locomotive  valves,  forms  R  and  S,  are  built  entirely  of  a  high 
grade  of  bronze,  except  the  springs  and  spindles,  which  are  of  steel. 

Specifications  for  each  valve  type  give  the  material  of  each  part 
in  detail. 

All  valves  before  leaving  the  factory  are  thoroughly  tested,  ad- 
justed, ground  in  and  set  under  the  same  pressure  conditions  of  service 
they  are  designed  for. 


Consolidated         Pop          Safety         Valves 

Stationary  Type 

For  Saturated  Steam 


Form  A 

This  type  of  valve  is  designed  for  general  stationary  work  on  saturated 
steam,  except  for  low  pressure  house  heating  and  other  small  boilers  where  the 
lighter  design,  forms  M  or  O,  can  be  used,  or  for  portable  and  exposed  boilers 
where  the  composition  body  forms  H,  1  or  K,  should  be  selected. 

Lock  up 

The  lock-up  attachment  of  each  valve  is  sealed  with  a  brass  tag  on  which  its 
guaranteed  capacity,  in  pounds  of  steam  per  hour,  is  stamped.  See  cut,  page  72.

Stationary  Type 

For  Superheated  Steam 


Form  B 

This  type  of  valve  is  especially  designed  for  service  under  superheated 
steam.  It  has  an  exceptionally  large  spring  to  meet  the  higher  temperature 
conditions  of  superheat  practice  and  should  be  selected  in  all  cases  where  there 
are  steam  temperatures  above  42o°F.  It  can  also  be  used  advantageously  for 
high  pressure  service  under  saturated  steam. 

A  superheat  safety  valve  should  be  applied  to  every  superheater,  in  order 
to  maintain  a  flow  of  steam  through  it  when  the  main  feed  is  suddenly  checked ; 
otherwise  the  superheater  becomes  a  dead  end,  and  under  such  conditions  it  is 
in  danger  of  serious  damage  by  the  excessively  high  temperatures. 

Lock  up 

The  lock-up  attachment  of  each  valve  is  sealed  with  a  brass  tag  on  which  its 
guaranteed  capacity,  in  pounds  of  steam  per  hour,  is  stamped.  See  cut,  page  72.

Consolidated         Pop         Safety         Valves 


Stationary  and  Marine  Types 

Instructions — Installation,  Adjustment 
and  Repairs 

These  instructions  apply  to  valves,  forms  A,  B,  C,  D  and  E,  and  are  sub- 
stantially as  given  upon  an  instruction  tag  which  is  wired  to  each  of  these  valves 
when  it  leaves  the  factory. 

Directions  for  Installation 

The  valve  must  be  connected  directly  to  the  boiler  with  a  close  nipple  or 
short  steam  noz/le  of  the  full  valve  size,  or  larger.  Under  no  conditions  should 
there  be  any  stop  valve,  fitting  or  extra  piping  between  it  and  the  boiler.  In 
applying  valve,  strain  up  the  flange  bolts  evenly.  Carelessness  in  this,  or  in 
handling  the  valve,  may  distort  its  seat  and  make  valve  leak.  New  boilers 
should  be  thoroughly  blown  out  before  the  safety  valve  is  used,  or  chips,  red 
lead,  cement,  etc.,  will  ruin  the  valve  seat.  The  valve  should  be  properly 
gagged,  during  hydraulic  and  other  testing,  instead  of  screwing  the  spring  down 
to  the  high  pressures  required. 

Directions  for  Adjustment 

All  valves  are  accurately  adjusted  and  tested,  before  leaving  the  factory,  and 
should  not  be  altered  until  necessary. 

Popping  Pressure 

First:  Remove  the  cap  and  lever.  To  do  this,  if  a  form  C,  Dor  E  valve,  with- 
draw the  cap  key,  lift  off  the  cap  and  remove  the  lever.  If  a  form  A  or  B  valve, 
take  out  the  lever  pin  and  lever,  turn  the  cap  a  quarter  turn  and  lift  it  off ;  remove 
the  cotter  pin  and  unscrew  the  release  nut  from  the  spindle.  Then  loosen  the 
check  nut  on  the  compression  screw  and  turn  the  screw  down  (right  handed)  to 
increase,  and  up  (left  handed)  to  decrease  the  popping  pressure.  A  quarter  turn 
of  the  compression  screw  will  change  the  popping  point  5  to  10  pounds.  The  check 
nut  should  be  tightened  and  valve  blown,  to  determine  the  result,  and  after  the 
correct  setting  is  obtained  the  cap  and  lever  should  be  replaced.  On  the  form 
A  and  B  valves,  however,  before  replacing  the  cap,  the  castellated  release  nut 
should  be  screwed  down  on  to  the  spindle  until  there  is  about  -jVinch  clearance 
between  it  and  the  top  of  the  compression  screw,  where  it  should  be  carefully 
pinned  with  the  cotter  pin.  Especial  care  must  be  taken  that  this  clearance 
between  the  release  nut  and  the  top  of  the  compression  screw  be  maintained, 
for  if  this  nut  touches  the  compression  screw  the  valve  will  be  held  open  and  leak. 

Note.  The  valve  spring  is  designed  for  the  pressure  stamped  on  the  brass 
tag  wired  to  the  valve.  If  valve  is  to  be  set  at  a  pressure  over  ten  (10)  pounds 
above  or  below  this  pressure  a  new  spring  should  be  furnished. 

Blowdown 

To  change  this,  remove  the  hex.  head  lock  screw  in  the  side  of  the  base 
casting,  insert  any  pointed  tool  and  turn  the  slotted  or  notched  adjusting  ring 

28 


Consolidated         Pop         Safety         Valves 


Stationary  and  Marine  Types 

Instructions — Continued 

down  (right  hand  rotation)  to  decrease,  and  up  (left  hand  rotation)  to  increase 
the  blow  down,  between  the  popping  and  the  closing  pressures.  Replace  the 
lock  screw  and  tighten  it  before  blowing  the  valve,  being  sure,  before  inserting 
it,  that  a  notch  of  the  ring,  to  receive  its  point,  comes  opposite  the  center  of  the 
hole. 

The  screw  should  always  shoulder  at  its  head  and  not  bear  upon  the  ring. 
In  setting  the  ring,  move  it  only  two  or  three  notches  at  a  time. 

If  the  valve  does  not  pop  cleanly  or  shows  a  tendency  to  rumble,  the  ring 
is  too  low  and  should  be  screwed  up  (left  hand  rotation).  It  is  not  advisable  to 
set  the  valve  to  blow  down  less  than  four  (4)  pounds,  and  if  it  does  blow  down 
less,  the  ring  should  be  put  up  to  prolong  the  life  of  the  valve. 

Directions  for  Repairs 

Before  taking  the  valve  apart,  if  it  is  a  form  A  or  B,  remove  the  cap,  and 
screw  the  release  nut  down  on  spindle  until  it  bears  upon  the  top  of  the  com- 
pression screw.  If  a  form  C,  D  or  E  valve,  leave  the  cap  and  key  in  place.  Then, 
upon  removing  the  valve  cover  bolts,  the  cover,  spring,  spindle,  etc.,  may  be 
removed  together,  without  releasing  the  spring  or  disturbing  its  adjustment. 

In  regrinding  these  valves,  remember  they  have  balled  and  not  straight 
taper  seats,  and  therefore  do  not  machine  the  seats  unless  absolutely  necessary. 
Grind  the  valve  with  No.  ^  pulverized  quartz  and  heavy  machine  oil,  using  a 
coarser  grade,  about  No.  il/2,  at  first,  if  the  surfaces  need  to  be  considerably 
cut  down,  and  finish  with  the  No.  l/2.  Be  sure  the  seats  are  wiped  clean  after 
grinding.  If  the  valve  needs  repairs  further  than  regrinding,  it  should  be  sent 
to  the  factory,  if  possible.  If  not,  special  instructions  should  be  requested  from 
The  Consolidated  Safety  Valve  Company,  85-89  Liberty  Street,  New  York.

Portable  Types 


These  valves  are  made  entirely  of  special  high  grade  bronze  composition, 
with  the  exception  of  the  spring,  spindle,  washers  and  lever.  They  are 
especially  adaptable  to  out-door  service  on  portable  boilers,  hoisting,  farm 
and  steam  fire  engines,  road  rollers,  steam  launches,  etc.  They  have  the  same 
adjustments  and  general  structural  features  throughout  as  the  iron  and  steel 
body  types  previously  described.  These  features  are  :  large  diameter  spring, 
the  ball  bearing  spring  washers,  the  low  spindle  bearing  on  the  feather,  the  long 
wing  bearings  and  the  Richardson  Adjusting  Ring. 

These  valves  are  made  with  three  different  types  of  outlet  or  exhaust,  the 
designs  being  exactly  similar  with  this  exception.  The  parts  are  interchangea- 
ble. They  are  made  in  all  pipe  sizes  from  %"-inch  to  3-inch. 

See  section,  page  11,  on  Consolidated  Safety  Valve  Designs,  for  a  descrip- 
tion of  the  general  features  of  these  valves.

body  valve  desirable. 

Form  H  should  be  selected  wherever  it  is  unnecessary  to  muffle  or  pipe 
away  the  steam  exhaust. 

Form  I  should  be  selected  if  it  is  desired  to  pipe  away  the  exhaust  steam, 
or  deflect  it  in  any  given  direction. 

Form  K  should  be  selected  wherever  it  is  unnecessary  to  pipe  away  the  ex- 
haust but  desirable  to  diminish  the  noise  of  its  discharge.

Lock-up  Attachment 


A  compact  and  neat  lock-up  attachment  for  application  to  any  of  the  port- 
able designs,  forms  H,  I  and  K,  will  be  furnished  when  ordered.  As  shown  in 
above  cut,  this  attachment  consists  of  a  simple  bronze  collar,  of  but  two  parts, 
which  covers  the  base  of  the  valve  cap,  making  it  impossible,  when  locked,  to 
remove  the  cap.  It  thus  effectually  protects  the  compression  screw  and  its 
pressure  adjustment  beneath. 

This  attachment  will  be  furnished  with  either  plain  seal  or  bronze  case  pad- 
lock as  specified.  It  may  be  ordered  either  with  the  valve  or  separately  for 
application  to  valves  already  in  service.  In  the  latter  case,  it  is  necessary 
merely  to  specify  the  size  of  the  portable  valve  for  which  it  is  desired.

Consolidated         Pop         Safety         Valves 


Portable  Types 

Instructions — Installation,  Adjustment 
and  Repairs 

These  instructions  apply  to  valves,  forms  H,  I  and  K,and  are  substantially 
as  given  upon  an  instruction  tag,  which  is  wired  to  each  of  these  valves  when  it 
leaves  the  factory. 

Directions  for  Installation 

These  valves  should  be  connected  to  the  boiler  as  directly  as  possible. 
Under  no  conditions  should  there  be  any  stop  valve,  fitting  or  extra  piping  be- 
tween it  and  the  boiler.  New  boilers  should  be  thoroughly  blown  out  before  the 
safety  valve  is  used  or  chips,  red  lead,  cement,  etc.,  will  ruin  the  valve  seat. 

Directions  for  Adjustment 

All  valves  are  accurately  adjusted  and  tested  before  leaving  the  factory, 
and  should  not  be  altered  until  necessary. 

Popping  Pressure 

To  change  the  pressure  at  which  the  valve  pops  or  opens,  remove  the  cap 
and  turn  the  compression  screw  down  (right  handed)  to  increase,  and  up 
(left  handed)  to  decrease  the  popping  pressure. 

Blow  Down 

To  change  this,  remove  the  hex.  head  lock  screw  in  the  lower  part  of  the 
case,  insert  any  pointed  tool  and  turn  the  slotted  or  notched  adjusting  ring  down 
(right  hand  rotation)  to  decrease,  and  up  (left  hand  rotation)  to  increase  the 
blow  down  between  the  popping  and  closing  pressures.  Replace  the  lock  screw 
and  tighten  it  before  blowing  the  valve,  being  sure,  before  inserting  it,  that  a 
notch  of  the  ring,  to  receive  its  point,  comes  opposite  the  center  of  the  hole. 
The  screw  should  always  shoulder  at  its  head,  and  not  bear  upon  the  ring.  In 
setting  the  ring,  move  it  only  two  or  three  notches  at  a  time. 

Directions  for  Repairs 

In  taking  these  valves  apart,  first  remove  the  lever  pin,  lever  and  cap.  The 
hole  at  the  top  of  the  lever  handle  is  threaded  to  fit  the  top  of  the  spindle. 
Screw  it  down  on  the  spindle  until  it  bears  upon  the  top  of  the  compression 
screw,  thus  locking  the  spring  compression.  Then  remove  hex.  head  adjusting 
ring  lock  screw  and  unscrew  the  case  from  the  base,  using  the  lugs  provided. 

The  valve  may  be  reground,  assembled  and  the  lever  removed  from  the 
spindle,  leaving  both  the  popping  pressure  and  blow  down  adjustments  un- 
altered. In  regrinding  these  valves,  remember  that  they  have  balled  and  not 
straight  taper  seats,  and  therefore  do  not  machine  the  seats  unless  absolutely 
necessary.  Grind  the  valve  with  No.  >£  pulverized  quartz  and  heavy  machine 
oil,  using  a  coarser  grade,  about  No.  \l/2,  at  first,  if  the  surfaces  need  to  be  con- 
siderably cut  down,  and  finish  with  the  No.  l/2.  Be  sure  the  seats  are  wiped 
clean  after  grinding.

Consolidated         Pop         Safety        Valve 


Water  Relief  Type 


Form  L 

This  type  of  valve  is  designed  for  general  service  in  relieving  the  pressure 
of  any  liquid  which  is  not  injurious  to  bronze  composition,  of  which  certain  of 
the  interior  parts  are  constructed. 

It  meets  the  requirements  of  the  Associated  Factory  Mutual  Fire  Insurance 
Companies  and  the  National  Board  of  Fire  Underwriters. 

It  is  specially  adapted  for  use  in  connection  with  steam  pumps  of  all 
kinds,  pipe  lines,  water  works,  etc.

Water  Relief  Type 

In  the  water  relief  valve,  form  L,  will  be  found  certain  changes  in  details 
of  construction,  from  those  in  the  various  types  of  Consolidated  Safety  Valves 
designed  for  service  under  steam.  These  variations,  as  well  as  other  features 
of  this  valve,  are  very  clearly  shown  in  sectional  view  on  page  42. 

These  details  of  construction,  which  are  peculiar  to  the  form  L  valve,  are 
necessary  to  perfectly  adapt  the  valve  to  the  work  required  of  it. 

As  indicated  on  page  40,  we  have  combined  in  this  valve  features,  which 
not  only  fit  it  for  the  general  service  required  of  valves  of  this  character,  but 
which  make  it  fully  meet  the  requirements  of  the  underwriting  boards. 

As  will  be  seen  from  the  sectional  view,  the  most  important  variation  in 
construction  is  the  design  of  the  feather.  It  will  also  be  noted  that  the  adjust- 
ing ring  which  is  employed  in  practically  all  of  the  other  types,  has  been  omitted 
in  the  form  L.

Consolidated         Pop         Safety        Valves 


Water  Relief  Type 

Instructions — Installation,  Adjustment 
and  Repairs 


These  instructions  apply  to  valves,  form  L,  and  are  substantially  as  given 
upon  an  instruction  tag,  which  is  wired  on  each  of  these  valves  when  it  leaves 
the  factory. 

Directions  for  Installation 

Connections  to  these  water  relief  valves  must  be  arranged  so  that  the  sup- 
ply of  liquid  will  not  be  throttled  or  restricted  by  small  piping,  excessive  length 
of  pipe  or  by  too  many  or  restricted  fittings  between  the  valve  and  its  source  of 
pressure. 

In  case  of  flanged  valves,  the  bolts  should  be  tightened  up  evenly.  Care- 
lessness in  this,  or  in  handling  the  valves  previous  to  application,  may  distort 
the  bodies  and  seats  and  cause  the  valves  to  leak.  All  connections  should  be 
blown  out  and  cleaned  before  the  valves  are  connected,  otherwise,  in  new  work 
especially,  pipe  cement,  scale  or  dirt  may  work  into  the  valve  openings,  become 
lodged  between  the  seats  and  cause  leakage. 

Directions  for  Adjustment 

Arrows  on  the  handwheel  indicate  the  proper  rotation  of  same  to  open  valve 
or  reduce  the  popping  pressure.  Reverse  motion  of  handwheel  will  close  the 
valve  or  increase  the  popping  pressure.  The  pronged  lock  nut  directly  under 
the  handwheel  should  be  loosened  before  attempting  to  move  the  handwheel 
and  well  tightened  after  adjustments  are  made. 

Directions  for  Repairs 

To  grind  these  valves,  back  out  the  spring  compression  screw  by  turning 
the  handwheel  in  the  direction  of  the  arrows  on  same.  Back  out  the  cover 
bolts  and  remove  the  cover.  All  this  can  be  done  without  disturbing  the  pipe 
connections.  Grind  the  valve  with  No.  y2  pulverized  quartz  and  heavy  machine 
oil,  using  a  coarser  grade,  about  No.  I  ^  at  first,  if  the  surfaces  need  to  be  consider- 
ably cut  down,  and  finish  with  No.  Yz.  Be  sure  the  seats  are  wiped  clean  after 
grinding.  If  repairs  other  than  grinding  are  needed,  send  the  valves,  if  possi- 
ble, to  the  factory.  If  not,  special  instructions  should  be  requested  from  The 
Consolidated  Safety  Valve  Company,  85-89  Liberty  Street,  New  York.

While  the  form  M  valve  is  adapted  for  low  pressure  work  only,  it  is  a  high 
grade  valve  in  every  respect,  having  a  design  which  makes  it  particularly  well 
suited  for  service  on  low  pressure  boilers.  The  materials  employed  in  its  manu- 
facture are  exactly  the  same  as  are  used  in  our  high  pressure  bronze  valves.  It 
has  a  liberal  capacity  and  clean  blow  which  are  characteristic  of  Consolidated 
Pop  Safety  Valves.  It  likewise  closes  sharply,  not  simmering  along  indefi- 
nitely as  many  valves  of  this  character  do. 

Although  the  form  M  valve  is  extremely  simple  in  construction,  it  is  of  such 
design  that  it  has  a  perfect  pop  safety  valve  action.  The  cap  enclosing  the 
compression  screw  is  also  the  check  nut.  The  spring  has  ball  bearings  at  both 
ends.  This  feature,  together  with  a  substantial  weight  feather  and  a  generous 
length  of  feather  wings,  is  peculiar  to  the  Consolidated  Valve  and  is  an  especi- 
ally advantageous  one  for  low  pressures  where  the  least  cramping  or  drag  will 
prevent  uniform  valve  action.  The  seat  is  the  bevelled  45  degree  type,  which 
always  insures  a  tight  valve  and  prevents  its  sticking. 

The  inside  attachment  of  the  lifting  lever  allows  an  exterior  finish  of  the 
entire  valve,  making  a  much  more  attractive  appearance  than  where  there  is  an 
unfinished  band  on  the  outside.  The  special  design  of  feather  in  the  Consoli- 
dated Valve  gives  an  action  exactly  the  same  in  principle  as  the  Consolidated 
high  pressure  valves. 

This  valve  is  very  readily  taken  apart  for  grinding  or  repairs.  Unscrewing 
the  case  by  means  of  the  hex.  nut  on  its  top,  exposes  the  entire  interior  of  the 
valve.  The  lower  spring  ball,  being  part  of  the  feather  casting,  forms  a 
convenient  handle  when  grinding. 

The  adjustment  of  popping  point  is  very  easily  accomplished.  No  special 
tools  are  required  and  there  are  no  small  pins  or  screws  to  lose.  A  monkey 
wrench  and  screw  driver  are  all  that  are  needed  to  connect  the  valve,  adjust  or 
take  it  apart.

Consolidated         Pop         Safety         Valves 


Massachusetts  Police  Type 


Form  O 

The  form  O  valve  has  been  designed  to  meet  the  specifications  of  the 
Massachusetts  District  Police,  and  conforms  fully  to  their  requirements.  It 
should  be  selected  for  service  on  all  boilers  of  8  horse-power,  or  over,  carry- 
ing a  steam  pressure  of  15  pounds  or  less,  where  no  licensed  engineer  or  fire- 
man is  employed. 

Lock  up 

This  type  of  valve  is  regularly  furnished  with  lock-up  attachment,  together 
with  padlock. 

50 


Consolidated         Pop         Safety         Valves 


Massachusetts  Police  Type 

The  general  construction  of  this  valve  is  similar  to  the  regular  house  heat- 
ing type  valve,  form  M,  as  will  he  seen  by  the  sectional  views  on  pages  48 

and  52. 

While  this  valve  is  adapted  to  all  pressures  up  to  30  pounds,  practically  all 
valves  of  this  type  furnished  are  set  at  15  pounds  or  less,  as  15  pounds  is  the 
maximum  allowed  under  the  above  law.  In  the  form  O  valve  will  be  found  the 
same  liberal  capacity  and  clean  blow  which  are  peculiar  to  the  regular  house 
heating  type  valve,  form  M.  These  valves  close  sharply  without  any  simmer 
whatever.  They  are  designed  to  withstand  the  highest  working  pressure  under 
which  valves  of  this  type  are  used  and  also  the  hard  usage  which  they  often 
receive  while  being  connected  to  the  boiler. 

The  form  O  valves  are  so  designed  that  all  the  requirements  of  the  law  are 
met  by  a  valve  which  is  symmetrical  and  compact  in  design  and  of  a  size 
which  is  in  proportion  to  the  boiler  on  which  it  is  installed. 

This  type  of  valve  can  very  easily  and  quickly  be  taken  apart  for  grinding 
or  repairs.  To  accomplish  this,  unscrew  the  case,  using  the  hex.  nut  on  base, 
and  thereby  expose  the  entire  interior  of  the  valve.  The  lower  spring  ball, 
being  part  of  the  feather  casting,  forms  a  convenient  handle  when  grinding. 

The  adjustment  of  the  popping  point  is  very  similar  to  that  em- 
ployed in  the  regular  house  heating  type,  form  M.  In  the  form  O  valve,  how- 
ever, this  cannot  be  accomplished  without  first  removing  the  padlock  which 
secures  the  cap  to  case  of  valve.  No  special  tools  are  required  to  change  the 
popping  point.  A  monkey  wrench  and  screw  driver  are  all  that  are  needed  to 
connect  the  valve,  adjust  or  take  it  apart.

Consolidated         Pop         Safety         Valves 


Ashcroft  Micrometer  Lift  Gauge 


For  the  quick  and  convenient  determination  of  the  lift  of  safety  valves, 
this  device  has  been  designed.  The  instrument  consists  of  an  indicating  dial, 
graduated  in  hundredths  and  half  hundredths,  starting  at  zero  and  extending 
through  a  range  of  twenty-five  hundredths  of  an  inch.  The  hundredth  divisions 
are  plainly  numbered  and  spaced  one-quarter  of  an  inch  apart. 

The  dial  and  indicating  hand,  with  the  gauge  movement,  are  enclosed  in  a 
brass  case  having  a  removable  glass  front.  The  gauge  case  is  attached  to  a 
frame  which  is  equipped  with  set  screws.  This  frame  can  very  readily  be  fitted 
to  the  top  part  of  safety  valve,  and  in  a  position  which  places  the  gauge  case 
directly  over  the  top  of  the  center  of  the  valve. 

From  the  gauge  case  a  rod  is  extended  so  that  it  may  be  brought  to  bear 
upon  the  top  of  the  valve  spindle  or  other  lifting  valve  parts.  This  rod  is  ad- 
justable so  that  a  zero  reading  may  be  obtained  on  the  dial  by  means  of  a  thread- 
ed sleeve  clamped  with  a  thumb  screw. 

This  device  is  small  and  compact  and  can  conveniently  be  added  to  an  in- 
spector's kit.

Locomotive  Types 


L)  CO  MOTIVE  service  presents  peculiar  conditions  which  re- 
quire special  features  in  safety  valve  design.  During  their 
application,  locomotive  valves  are  frequently  in  almost  contin- 
ual action.  The  boilers  are  quick  steamers,  the  load  fluctuating  and 
the  valves  are  apt  to  receive  repeatedly  the  most  severe  conditions 
possible.  All  locomotive  apparatus,  especially  in  bad  water  districts, 
is  necessarily  subjected  to  frequent  inspection  and  should  therefore  be 
designed  with  reference  to  the  usual  round  house  facilities  for  this 
work.  For  such  reasons  the  locomotive  forms,  R  and  S,  while  in- 
corporating the  general  construction  of  all  Consolidated  Valves  (see 
page  11)  have  special  features,  designed  to  meet  the  exacting  require- 
ments of  locomotive  service  and  to  facilitate  their  inspection  and 
repair. 

The  encased  valve,  form  R,  and  the  muffler,  form  S,  have  identi- 
cally the  same  construction,  all  parts  being  interchangeable  except  for 
the  two  muffler  shells,  which  are  added  to  the  open  valve  in  making 
the  muffler.  The  practical  advantage  of  this  feature,  which  is  found 
only  in  the  Consolidated  Valve,  is  evident.  The  same  gauge,  instruc- 
tions or  set  of  repair  parts  apply  to  both  valves.  In  fact  a  muffler 
valve  can  be  converted  into  an  encased  one  by  merely  removing  its 
muffler  shells. 

Another  equally  important  advantage  results  from  this  form  of 
construction.  When  it  becomes  desirable  to  clean  the  muffler  shells 
of  lime  or  other  sediment,  either  by  reaming  out  the  holes  or  by  im- 
mersion in  an  acid  bath,  it  is  not  necessary,  as  is  the  case  with  all  other 
muffler  valves,  to  remove  the  valve  from  the  locomotive,  or  even  to 
alter  either  of  its  adjustments.  The  outer  muffler  shell  is  merely  un- 
screwed, both  shells  lifted  off  and  taken  to  the  bench  for  cleaning. 
This  removing  of  the  muffler  may,  of  course,  be  done  while  the  engine 
is  under  steam.  In  fact,  if  it  is  not  convenient  to  clean  the  shells  at 
once,  the  engine  can  make  a  trip  or  two  with  them  off.  The  valve 
will  work  perfectly  as  an  encased  valve,  under  these  conditions,  until 
the  shells  are  ready  to  be  replaced. 

55 


Consolidated         Pop         Safety        Valves 

The  open  construction  of  compression  screw  and  check  nut  at  the 
top  does  away  with  the  cap  of  other  designs.  These  caps  are  incon- 
venient and  unnecessary.  They  restrict  the  amount  of  metal  upon  the 
top  hex  of  the  compression  screw  and  also  its  length,  at  the  top,  avail- 
able for  taking  up  wear.  Further  they  must  be  taken  completely  off 
and  replaced  whenever  adjusting  the  valve.  As  a  result  round-house 
men  generally  remove  them  or  turn  off  their  tops.  In  adjusting  the 
Consolidated  Valve,  on  the  other  hand,  it  is  merely  necessary  to 
loosen  the  check  nut  a  fraction  of  a  turn.  This  nut  cannot  be  lost 
or  removed  over  the  top  of  the  compression  screw  for  the  screw  has  a 
large  heavy  hex.  head  that  will  stand,  without  crushing,  the  rough  usage 
it  is  apt  to  receive.  Also  the  threaded  part  of  the  screw  above  the  check 
nut,  available  for  taking  up  wear,  has  been  left  exceptionally  long. 

The  steam  discharge  from  these  valves  is  all  vertically  upwards, 
there  being  no  side  blow  or  spreading  out  of  the  steam  to  cloud  the 
cab  windows.  This  desirable  result  is  obtained  by  placing  the  spring 
case  vent  holes  at  the  top  of  the  case  instead  of  at  the  side  and  by 
drilling  the  outer  muffler  shell  in  a  special  jig,  by  which  the  direction 
of  the  holes  is  kept  nearly  vertical. 

If  damage  to  the  valve  seat,  due  to  a  chip  or  other  cause,  makes 
it  necessary  to  reseat  the  valve,  the  shape  of  the  disc  has  been  so  sim- 
plified, that  a  single  lathe  cut  across  the  horizontal  surface,  just  out- 
side the  seat,  is  all  that  is  required  to  properly  maintain  its  shape. 
Grooving  of  the  steam  across  the  valve  seats  at  a  point  opposite  the 
wings  of  the  feather  or  disc,  a  very  common  difficulty,  has  been  com- 
pletely overcome  in  this  design  by  milling  the  wing  faces  to  a  point  at 
their  top  just  beneath  the  seat. 

The  construction  of  Consolidated  Locomotive  Valves  throughout 
is  of  the  simplest,  most  straightforward  design  giving  an  absolutely 
minimum  number  of  parts,  there  being  a  total  of  but  twelve  parts  to  the 
encased  valve  and  but  three  more  to  the  muffler. 

Although  the  preceding  paragraphs  have  merely  enumerated  some 
of  the  mechanical  details  of  the  forms  R  and  S  valves,  the  funda- 
mental principles  of  Consolidated  design  and  action  are  all  incorporated 
in  them.  The  principal  of  these  features  are  the  exceptionally  large 
springs  with  their  correspondingly  low  fibre  stresses ;  the  flexible 

56 


Consolidated         Pop         Safety        Valves 

mounting  of  both  ends  of  the  spring  with  top  and  bottom  washers, 
which  are  interchangeable  and  bear  each  upon  a  sensitive  balled  joint 
at  the  center ;  the  long,  broad-faced  wing  guides  of  the  valve  feather, 
or  disc ;  the  low  spindle  bearing  upon  feather ;  the  outside  overlap  of 
the  feather  trunk  upon  the  case  above,  over,  instead  of  into  which  joint 
the  steam  discharge  flows.  This  construction  leaves  no  area,  upon 
the  top  of  the  disc  or  feather,  exposed  to  the  steam  in  the  valve  case. 
The  action  of  the  valve  is  clean  and  positive  and  its  capacity  ap- 
proximately double  that  of  average  types.  The  closing  is  especially 
characteristic,  it  taking  place  from  nearly  the  full  lift  of  the  valve,  bit- 
ing off  the  steam  sharply  and  thus  protecting  the  seats  from  the  wire 
drawing  action  of  a  low  settling  close.

Standard    Equipments 

As  indicated  in  the  section  of  this  catalogue  on  Safety  Valve  Capacity 
(pages  9  and  10),  two  peculiar  conditions  of  locomotive  service  necessitate  in 
the  capacity  formula,  a  special  constant,  based  on  heating  surface.  A  value  for 
this  constant  has  been  experimentally  determined  after  exhaustive  service  tests, 
upon  locomotives  of  different  types  and  sizes,  on  various  railroads. 

Using  the  capacities  of  Consolidated  Pop  Safety  Valves,  Locomotive  Types, 
the  following  table  of  locomotive  safety  valve  equipments  has  thus  been  com- 
piled. When  Consolidated  Valves,  forms  R  or  S,  are  applied  in  accordance 
with  this  table,  it  will  not  be  possible  to  force  the  boiler  pressure  above  the 
popping  point  of  the  highest  set  valve.

Valve  Bases 

The  standard  threading  of  Consolidated  Locomotive  Valve  Bases  is  given 
below.  Except  in  the  il/2  inch  valve,  the  threads  are  straight  (not  taper).  The 
valve  bases  bottom  on  a  shoulder  of  the  spud  bushing  and  the  threading  is  al- 
ways female  in  the  valve  base.

Bushings 

Bushings  or  spuds  for  connecting  form  R  valves  to  boilers  will  be  furnished, 
when  specified.  Our  standard  bushings  are  threaded  at  the  top  end  to  fit  the 
standard  threading  of  valve  bases  given  in  above  table.  If  special  threading  is 
ordered  for  valve  base,  bushings  wilTbe  threaded  to  fit  same,  and  in  this  case  a 
male  thread  gauge  should  be  furnished  so  as  to  insure  that  this  special  thread- 
ing of  bases  properly  fits  the  railroad  standard.  Lower  end  of  bushing  will  be 
threaded  with  male  pipe  thread  of  size  corresponding  to  nominal  valve  size. 
Special  bushings,  threaded  to  other  than  our  standard  or  left  blank  for  turning 
to  make  press  fit,  will  be  furnished  when  specified,  it  being  our  practice,  in  case 
bushings  are  to  be  pressed  into  dome,  to  leave  the  lower  end  rough  turned 
slightly  larger  than  the  specified  size  so  that  the  final  fit  may  be  made  in  the 
railroad  shop.

Consolidated         Pop         Safety        Valves 


Locomotive  Types 

Instructions — Adjustment  and  Repairs 

Taking  Apart 

If  the  safety  valve  is  fitted  with  the  muffler,  be  sure  to  remove  the  locking 
screw  in  the  lower  rim  of  the  outside  muffler  shell  before  attempting  to  unscrew 
the  shell  from  the  valve  case.  Note  on  the  lower  part  of  the  muffler  shell  that 
there  are  lugs,  which  should  be  used  when  unscrewing  the  muffler  shell.  When 
it  is  desired  to  remove  the  case  from  the  base,  remove  the  ring  pin  and  unscrew 
the  case,  using  the  lugs  provided.  If  the  holes  in  the  muffler  shells  are  filled 
with  lime,  scale  or  dirt,  they  should  be  thoroughly  cleaned  by  scraping,  or  by 
immersion  in  a  suitable  bath,  the  nature  of  which  depends  upon  the  kind  of 
scale  to  be  cut  and  dissolved.  See  that  the  drainage  holes  in  the  feather  or 
disc,  in  the  adjusting  ring,  case  and  inner  muffler  shell  are  clean  and  free. 

Repairs 

In  order  that  the  safety  valve,  when  repaired,  may  be  maintained  in  the 
same  condition  as  when  new,  a  seating  gauge  and  cutter  (6")  and  a  feather  or 
disc  gauge  (F)  should  be  used. 

Valve  Seat 

If  the  valve  seat  needs  re-seating,  it  should  be  done  by  the  use  of  the  seat 
gauge  G.  This  gauge  has  a  hardened  edge,  and  by  clamping  it  to  a  flat  tool  can 
itself  be  used  as  a  cutting  tool  for  truing  up  the  valve  seat.  A  very  light  cut 
should  be  taken.  If  the  valve  seat  needs  any  great  amount  of  facing,  the  seat 
should  be  faced  with  a  regular  tool  and  finished  with  the  seat  gauge  G.  The 
seat  gauge  G  is  of  the  exact  radius  desired  for  the  seat,  and  care  should  be  taken 
when  using  it  as  a  cutting  tool  that  it  is  held  central,  to  give  the  seat  a  true  radius. 
When  the  seat  is  recut  it  will,  of  course,  increase  the  width  of  the  seat,  and  a 
cut  should  be  taken  off  the  top  of  the  base  to  reduce  the  seats  to  the  following 
widths  :

Feather  or   Disc 

This  seldom  needs  any  repairing  further  than  regrinding  and  no  machine 
work  should  be  done  upon  it  unless  absolutely  necessary.  If,  however,  its  seat 
has  become  marred  and  must  be  refaced,  chuck  the  feather  and  follow  opera- 
tions in  3rd,  4th,  5th  and  6th  sections  on  opposite  page.  If  in  addition  the 
feather  wings  are  found  to  have  worn  to  more  than  .05  inches  or  .06  inches 
diameter  play,  then  follow  all  the  operations  given.

Instructions — Continued 

It  is  very  important  in  making  repairs  that  the  feather  or  disc  have  the 
same  dimensions  when  repaired  as  when  new,  and  the  following  should  be  care- 
fully adhered  to  : 

ist.  Pein  out  the  feather  wings  not  striking  on  the  broad  bearing  faces  (a) 
but  on  the  web  within  (b). 

2nd.  Chuck  the  feather  by  the  thread  on  its  top  (e)  and  take  a  cut  off  the 
face  of  the  wings  (a),  truing  these  up  until  they  fit  into  the  base  with  about 
.01  inch  diameter  play. 

3d.  Take  a  light  cut  from  (c),  just  enough  to  true  it  up,  and  take  an  equal 
cut  from  the  bottom  of  the  wings  (d). 

The  feather  gauge  (F)  is  made  to  register  along  the  face  of  the  feather 
wings  (a)  and  should  be  used  in  the  following  operations  ;  great  care  should  be 
taken  in  repairing  the  feathers  to  bring  them  exactly  to  gauge.

Instructions  —  Continued 

Grinding  in  the  Seat 

Grind  the  valve  with  No.  %  pulverized  quartz  and  heavy  machine  oil,  using 
a  coarser  grade,  about  No.  i^,  at  first,  if  the  surfaces  need  to  be  considerably 
cut  down,  and  finish  with  the  No.  yz.  After  it  is  ground,  wipe  the  surfaces  per- 
fectly clean  and  rub  them  together  dry.  The  polished  surfaces,  which  are  the 
true  bearings,  should  start  from  the  bottom  edge  of  the  seat  and  appear  about 
3/32  inch  wide  in  valves  2^  inches  and  larger.  The  bearings  in  i^  inch  and 
2  inch  valves  should  be  about  Vie  inch  wide. 

To  insure  a  clean  working  valve,  this  seat  must  be  kept  down  to  the  loca- 
tion indicated,  and  if  any  bearing  points  appear  above  the  given  location,  they 
must  be  removed  with  emery  cloth,  being  careful  not  to  round  the  upper  corner 
of  the  seat. 

Assembly 

In  putting  the  valve  together,  the  adjusting  ring  should  be  placed  so  that  its 
top  horizontal  surface  is  about  X  °f  a  turn  below  the  top  of  the  base,  closer 
adjustment  to  the  desired  blowdown  being  made  by  trial  after  the  valve  is 
under  steam. 

Setting  Valve— For  Popping  Point 

In  adjusting  the  popping  point  of  the  valve,  loosen  the  check  nut  and  turn 
the  compression  screw  down  to  increase  and  up  to  decrease  the  popping  point. 

The  spindle  should  be  free,!,  e.,  central  in  the  top  of  the  compression  screw. 
If  it  bears  upon  one  side,  it  should  be  driven  to  the  center,  which  can  be  very 
readily  done.  Be  sure  to  tighten  the  check  nut  as  soon  as  the  correct  popping 
adjustment  is  made. 

For  Blowdown 

For  this  adjustment,  the  hex.  head  adjusting  ring  lock  screw  near  the 
bottom  of  the  case  is  removed  and  a  pointed  tool  of  any  kind  used  to  move  the 
slotted  ring.  The  adjusting  ring  thread  is  right-handed,  and  to  increase  the 
blowdown  (between  the  opening  and  closing  pressures  of  the  valve)  the  ring 
is  screwed  up;  to  decrease  the  blowdown  the  ring  is  screwed  down. 

Before  replacing  the  lock  screw,  be  sure  that  the  ring  is  left  with  a  slot 
opposite  the  center  of  the  hole,  otherwise  the  screw  may  strike  a  land  before 
seating.  This  screw  should  always  shoulder  at  its  head  and  not  bear  upon  the 
ring,  to  insure  a  tight  valve. 

In  setting  the  ring,  move  it  only  a  few  (4  to  5)  notches  at  a  time. 

If  the  valve  does  not  pop  cleanly  or  if  it  shows  a  tendency  to  rumble,  the 
ring  is  too  low  to  control  the  valve  and  should  be  screwed  up.  It  is  not  advisa- 
ble to  set  the  valve  to  blow  down  less  than  3  to  4  pounds,  and  if  it  does  blow 
down  less  the  ring  should  be  put  up.

Capacity  Tag 


To  each  Consolidated  Pop  Safety  Valve,  forms  A,  B,  C,  D,  E,  H,  I  and  K,  is 
attached  a  tag  same  as  shown  in  cut  on  this  page.  On  this  tag  will  be  found 
the  guaranteed  capacity  of  the  valve  in  pounds  of  steam  per  hour.  This  is 
the  capacity  which  this  company  guarantees  for  the  valve  in  question.  The 
figures  given  on  this  tag  have  been  arrived  at  by  actual  capacity  tests  and  can 
be  absolutely  relied  on  by  any  engineer  drawing  specifications  or  operating  the 
valves. 


Testing  Lugs 


Testing  lugs  will  be  furnished  with  safety  valves,  forms  A,  B,  C,  D  and  E, 
when  specified.  These  testing  lugs  or  clamps  will  prevent  any  strain  on  the 
spring  and  liability  of  injury  to  it,  when  boilers  are  being  tested.
